Geological Characteristics and Mineralization Potential of the Dazhuanggou Molybdenum Deposit in Songxian County,Henan Province

The Dazhuanggou is a newly discovered molybdenum deposit in the eastern section of the well-known East Qinling poly-metallic mineralization belt.A complete model of stratiform molybdenum mineralization is present at Dazhuanggou with assemblage of different style mineralization composed of quartz vein,altered rock and altered rhyolite porphyry.The geology,ore deposit characters,ore-controlling factors and mineralization stages are discussed,the mineralization is obviously controlled by strata,structure and magmatic rocks,and the it is a meso-epithermal hydrothermal infilling stratiform deposit mainly controlled by the interlayer fractures of strata.The paper summarized the ore-forming conditions,characteristics of ore deposits,metallogenetic factors and mineralization laws,and concluded that there is still great ore-forming potential in deeper parts and the deposit which could be medium size at least.
